SPECIFICATION forming part of Letters Patent No. 748,138, dated December29, 1903. Application filed November 18,1902- Serial No. 131.876. (Nomodel.)

To all whom it may concern.-

Be it known that we, GEORGE WILLIAM Zo- DER and WILLIAM PHILIP HAYNE,citizens of the United States, residing at Boyce, Rapids parish, andState of Louisiana, have invented a new and usefulrPress for OleaginousSubstances, of which the following is a specification. 1

This invention relates to presses for oleaginous substances.

The press of the present invention is an improvement of two patentsissued to usnamely, No. 649,503, dated May 5, 1900, and No. 691,430,dated January'31, 1902.

The objects of the present invention are generally to increase theefficiency of the pressing mechanism, resulting in a quicker operationof the press, a reduction of friction in the press-box, and theattainment of equal pressure on the top and bottom of the charge ofmaterial being pressed; to render it possible to form an oil-cake of thedesired form or to press cakes of less area than theinternal diameter ofthe ram-cylinders toimprove the manner of disposing the divisiomplateswithin the charging-box and to efiect I this without the necessity ofstopping the carriage for the insertion of such plates; to 0bviate wasteof the oil-bearing material; to regulate the thickness of the cake; to'provide a novel means for heating the contents of the press-box beforestarting the press; to effect automatic discharge of the cakes from thepress, and finally to improve various parts of the apparatus in a mannerthat will be hereinafter fully set forth.

With the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a press for oleaginoussubstances, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andinwhich like characters of reference indicate correspond: ing parts,there are illustrated two forms of embodiment of the invention, eachcapable of carrying the same into practical operation, it beingunderstood that the elements therein exhibited may be varied as toshape, proshown in Fig. 1.

portion, and exact manner of assemblage without departing from thespirit thereof.

In the drawings, Figure 1 is a view in ele- Vation, partly in section,of a press embodying the essential features of the present invention.Fig. 2 is a view in vertical longitudinal section of the chargingportion of the press. Fig. 3 is a view in side elevation,

' partly in section, of a modified form of press.

Fig. 4 is a view in plan of Fig. 1.

One of the salient points of improvement of the present invention isshown in Fig. l

. and consists in the provision of two ram-cylinders 1 and 2, which maybe of the usual or any preferred construction and are connected bypillars 3. In the patents to which reference has been made there isbutone ram-cylinder employed, the upper one in this case. The presentinvention resides in the addition of the ram-cylinder 2, disposed invertical alinement, the object of the employment of two cylinders beingto expedite the operation of the press, reduce the friction in thepressbox, and to obtain equal pressure on the top orbottom of the chargeor other material being pressed. The precise construction of theram-cylinders is immaterial and may be of any preferred type. There is,however, a change of construction in the rams in order to make the formof cake desirable or to press cakes of less area than the internaldiameter of the ram-cylinders, and this is effected by reducing thediameter of the lower portion of the'ram 4 and the lower portion of theram 5 at 6 and 7, respectively, leaving a space between the reducedportion of the rams and the inner walls of the cylinders, as clearly Theupper and lower ends of therespective rams form pistons, which snuglyfit Within the cylinders and are provided with the usual packing 8 forthe purpose; The piston portion of each of the rams is to be ofsufficient length to insure proper vertical movement thereof. To limitthe downward movement of the upper ram,-there is provided a collar orstoplO, and above the plane that will be occupied by the ram 4 when inits lowered position thereisprovided a relief-pipe 11, as usual.

Fitted around the upper end of the lower IOC ram 5 is a trough or tray12, which is designed to catch the downward flow of oil from thepress-box 13, Fig. 3, whence it is spouted to a tank or other convenientreceptacle, (not -shown,) thus to prevent any oil from the upinvention,and the mechanism for controlling the operation of the ram may be thesame as that shown in Patent No. 691,430 or of any other preferreddesign. Bolted to and projecting from the base of the press box is ahorizontally disposed bracket 15, and secured to the pillars 3 andextending beneath the press-box are a pair of trackways 16. (Clearlyshown in Fig. 4.) Depending from the outer end of the bracket are a pairof columns 17, the lowerends of which are secured to a ram 18, thecylinder of which is bolted at 19 to the cylinder 2. The said ram hasassociated with it a vertically-movable follower 20, as usual.

Mounted for movement upon the tracks 16 is a charging-box 21, thearrangement being such as to permit of said box being run under thepress-box and disposed in vertical aliuement therewith and with the rams4and 5. Y The box has its sides 22 hinged, thus to allow of the sidebeing opened to permit the charging-box being run over the follower 24of the ram 2, as shown in Fig. 1. When the side 22 is closed, it isheld'in that position by a bar 25 or other suitable means. In oppositesides of the charging-box, at the lower end thereof, are vertical slotsor openings, in which are pivoted pawls 26, and hinged to one side ofthe box is a coupling-hook 27.

Mounted in suitable bearings upon the bracket is a rock-shaft 28, withwhich is associated a lever 29, and to the shaft is connected a rock-arm30, from which depend clamps 31, which are adapted to engage ledges orflanges 32 on the sides of the chargingbox. By pressing the lever 29 theclamps may be caused to engage with the flanges 32 when the charging-boxis run outward under the press-box to the position shown in Fig. 1 anddirectly over the follower 20 of the ram 18, the said clamp operating tolock the charging-box in this position.

Extending from the upper portion of the cylinder 2 and above and on eachside of the follower 20 is a pair of tracks 33, the outer ends of whichare supported in any suitable manner, as by standards 34. Arranged asuitable distance above the tracks 33 is a hop.- per 35, having itsupper and lower ends open, the said hopper being supported at the properdistance above the tracks by plates 36. Running upon the tracks is acarriage 37, carrying a measuring-box 38, having mounted therein a falsefollower 39, the height of which is equal to the depth of themeasuring-box, the crossesection of which corresponds to that of thecharging-box 21, and the internal diameter of which conforms in size andshape against an angle-bracket 43, which bracket will insure that thedivision-plate will be properly disposed within the measuring-box as thelatter recedes, reciprocatory motion being imparted to the carriagethrough the medium of a piston-rod 44, carrying a piston working in acylinder45, supported by the uprights 34. Disposed in alinement with thetop of the follower 20 when the same is in the position shown in Fig. 1are a pair of skids 46, which are preferably pivoted at 47 to thetracks, that portion of the skids adjacent to the cylinder 18 beingupwardly inclined and that portion disposed beneath the hopper 35 beingstraight, the latter portions of the skids resting upon setscrews 48, bywhich they may be raised or lowered, thus to regulate the thickness ofthe cake. The set-screws are disposed in plates 49, bolted to the sidesof the tracks 33. In the operation of the machine when the carriage ismoved forward the false follower rides up the skids 46 and carries adivision-plate, which is deposited upon the said follower through themedium of the angle-bracket 43 beneath the hopper, where the charge ofmeal or other material is deposited, and on the outward movement of thecarriage the false follower moves down the skids, the upward movement ofthe said follower causing the equalizing-bars to remove any surplusmeal, and thus prevent waste, and the downward movement of the saidfollower causing it to be brought into operative relation with regard tothe follower 20. The provision of the adjustable skids is important,inasmuch as the thickness of the cakes to be pressed may be regulated atwill. When the carriage has moved rearward until the false follower isin position above the ram 20, the upward movement of the ram will raisethe false follower and the division-plate resting thereon to convey thecharge of meal into the charging-box, and upon the descent of the ramthe false follower will descend with it, and the divisionplate will besustained within the chargingbox by frictional engagement with the sidesthereof. When the ram 20 has reached the bottom of its descent, thecarriage will be ICC ready for another forward movement into positionunder the hopper 35 to receive a second charge of meal.

Carried by the forward end of the measuring-box is a coupling-hook 50,adapted to engage with the hook 27.01: the charging-box, thus to connectthe charging-box with the measuring-box to enable the latter when thesame is drawn to the position shown in Fig. .1 to draw the charging boxto the position shown in Fig. 2 over the follower 20.

As herein shown, the cylinder 45 is horizontally disposed, and asuitable valve 51 is provided to regulate the flow of fluid through thesupply-pipes 52, connecting with the respective ends of thecylinders,the valve being operated through the medium of a connectingrod 53, connected with an operatinglever 54.

To effect discharge of the cake from the press, bars 55 are employed,which are disposed within grooves in the upper face of the follower 24and are connected by chains 56 to the upper cylinder. When the rams areapproaching each other, these bars lie in the grooves of the followerand do not interfere with the pressing action of the machine;v but onthe downward movenfent of the ram these bars are lifted to the positionshown-in Fig. 1, and thus efiect discharge of the cake.

In Fig. 3 is shown a slightly-modified form of press-box, wherein theends 57 thereof are hollow, as shown at 58, to constitute steam-'chambers, steam supply and exhaust pipes 59 and 60, respectively, beingassociated with the chambers to eifect their heating. By initiallyheating the meal before subjecting it to pressure the oil is started andwill be more readily given up. The form of apparatus shown in Fig. 3 isadapted for use in mills having two or more presses and but one chargingapparatus for any number of presses. To accomplish this result, there isdisposed above the lower cylinder of each press, of

which there are shown in this instance two, a circular track 61, uponwhich travels the wheels 62 of a turn-table63,carrying sections By thisarrangement the employment prising two vertically-alined ram-cylinders,and an oil-catching device adapted to be raised by the lower ram whenthe same has reached a predetermined point in lifting.
